Google teatas kuueaastase projekti j\u00e4rel OpenTitan avatud platvormil p\u00f5hineva kiibi tootmise algusest. Kiibi toodab ettev\u00f5te Nuvoton ja see on m\u00e4rgitud kui esimene OpenTitani rakendus, mis on valmis tootmisprojektide jaoks. Hetkel on testimiseks vabastatud katsetustooted ja massilise tootmise algust plaanitakse k\u00e4esoleva aasta kevadel. <\/p>\n

OpenTitan on platvorm usaldusv\u00e4\u00e4rsete riistvarakomponentide (RoT, Root of Trust) loomiseks, mida kasutatakse seal, kus on vajalik tagada s\u00fcsteemi riist- ja tarkvara elementide terviklikkus. N\u00e4iteks selleks, et kinnitada, et s\u00fcsteemi kriitilised osad pole vahetatud ning p\u00f5hinevad tootja poolt kinnitatud ja kontrollitud koodil. Projekt pakub valmis ja testitud raamistikku, mis v\u00f5imaldab suurendada usaldusv\u00e4\u00e4rsust loodud lahendustele ja v\u00e4hendada spetsialiseeritud turvakiipide arendamise kulusid. <\/p>\n

OpenTitani kiipe saab kasutada serverite emaplaatidel, v\u00f5rgukaartidel, tarbimistoodetel, marsruuterites ja asjade interneti seadmetes, et kinnitada p\u00fcsivara ja laetavaid komponente, genereerida kr\u00fcptograafiliselt unikaalseid s\u00fcsteemi identifikaatoreid (riistvara vahetuse kaitse), pakkuda turvalisusega seotud teenuseid, kaitsta kr\u00fcptograafilisi v\u00f5tmeid (ainult v\u00f5tmete isolatsioon, kui r\u00fcndaja omandab f\u00fc\u00fcsilise ligip\u00e4\u00e4su seadmetele) ja pidada eraldatud auditi logi, mida ei saa muuta ega kustutada. <\/p>\n

OpenTitan sisaldab RoT-kiipides n\u00f5utud loogikablokke, nagu avatud RISC-V arhitektuuril p\u00f5hinev mikroprotsessor (RV32IMCB Ibex), kr\u00fcptograafilised ko-protsessorid, riistvaraline juhuslike numbrite generaator, DICE toe jaotamise v\u00f5tmehaldur, turvalise andmesalvestuse mehhanism p\u00fcsivajas ja m\u00e4les, kaitsetehnoloogiad, sisendi\/v\u00e4ljundi plokid ja turvalise k\u00e4ivitamise komponendid. Seade pakub samuti plokke t\u00fc\u00fcpiliste kr\u00fcptimisalgoritmide, nagu AES ja HMAC-SHA256, rakendustega ning matemaatikaoperatsioonide kiirendit, mida kasutatakse digitaalsete allkirjade loomise algoritmides avalike v\u00f5tmete alusel.

Projekt on rajatud Google'i poolt, kuid edastatud mittetulundus\u00fchingule lowRISC, p\u00e4rast mida liitusid selle arendusega sellised ettev\u00f5tted nagu Western Digital, Seagate, Nuvoton Technology, Winbond, Rivos, zeroRISC ja G+D Mobile Security. Projekti raames avaldatud kood ja riistvarakomponentide spetsifikatsioonid on litsentseeritud Apache 2.0 all. OpenTitanis rakendatavates lahendustes on kasutatud juba olemasolevaid tehnoloogiaid nagu Google Titan kr\u00fcptograafilised USB-tokenid ja TPM-kiibid, et tagada kontrollitud laadimist. serverites<\/a> Google'i infrastruktuuris ning ka Chromebooki ja Pixel seadmetes. <\/p>\n

Erinevalt olemasolevatest Trust Rooti lahendustest arendab OpenTitan end l\u00e4bipaistvuse kaudu turvalisuse kontseptsiooni j\u00e4rgi, mis h\u00f5lmab koodi ja skeemide kergesti k\u00e4ttesaadavust ning t\u00e4iesti avatud arendusprotsessi, mis ei ole seotud \u00fchegi konkreetse tarnija v\u00f5i kiibitootjaga. OpenTitan on turule toodud esimene avatud Trust Rooti lahendus, millel on post-kvantmehaanika turvalise k\u00e4ivitamise toetus, mis p\u00f5hineb SLH-DSA (Sphincs+) digitaalsete allkiri genereerimise algoritmil, mis on vastupidav kvantarvutite r\u00fcnnakutele.
